Technical Field

[0001] The utility model relates to an air intake bus, in particular to an air intake bus which is used in conjunction with a dust removal system and is arranged on the top of the dust removal system. Background Art

[0002] The existing traditional manufacturing or foundry industry will generate a certain amount of dirty air during the production process. Since the dirty air contains a large amount of dust or other large particles, it is necessary to collect the dirty air and send it to the dust removal system for filtration and dust removal before it can be discharged to avoid pollution to the environment. Most of the dust removal systems in the existing technology use side air intake. If the dirty air discharge volume is greater than 90,000m 3 / h, when the dust content is large, the dust is abrasive and sticky, then this type of dust removal system is not suitable for this environment. The reason is that the conventional side air intake structure will make the air volume uneven, and the air volume mainly acts on the filter element close to the dirty air inlet, which can easily cause the filter element at this position to be damaged, affecting the filtering effect and requiring frequent replacement; at the same time, if the dirty air discharge volume is very large, the structural size of the side air intake will also be relatively large, resulting in poor strength and aesthetics of the structure, as well as inconvenience in installation and transportation.

[0006] The interior of the dirty air guide chamber is provided with dirty air guide components which correspond to the air outlet of the air inlet chamber and are arranged in multiple rows in a staggered manner. Gaps are left between adjacent dirty air guide components in the same row, and this gap forms a gas flow channel with the sides of the dirty air guide components on both sides.

[0009] In the above technical solution, the air inlet chamber has a plurality of branch chambers connected to its main body, and each branch chamber is connected to the dirty gas diversion chamber. At the same time, the air outlet of each branch chamber is arranged relative to a group of multiple rows of staggered dirty gas diversion components in the dirty gas diversion chamber.

[0014] In the above technical solution, the top surface of the air inlet chamber is designed to be inclined to prevent rust due to accumulated water.

[0015] The positive effect of the utility model is that after the top air intake bus of the dust removal system of the utility model is adopted, since the utility model includes an air intake chamber and a dirty air guide chamber,

[0023] The present invention is further described below in conjunction with the accompanying drawings and given embodiments, but is not limited thereto.

[0024] like Figure 1 ,2 As shown in , 3 and 4, a top air intake bus of a dust removal system includes an air intake chamber 1 and a dirty air guide chamber 2.

[0025] The air inlet chamber 1 has a dirty air inlet 11, and the air inlet chamber 1 is connected to the top of the dirty air guide chamber 2. The dirty air guide chamber 2 is installed on the top of the dust removal system, and the bottom of the dirty air guide chamber 2 is connected to the air inlet provided on the top of the dust removal system 6.

[0026] The interior of the dirty gas guide chamber 2 is provided with dirty gas guide components 3 corresponding to the air outlet of the air inlet chamber 1 and arranged in multiple rows in a staggered manner. There is a gap between adjacent dirty gas guide components 3 in the same row, and this gap forms a gas flow channel with the side surfaces of the dirty gas guide components 3 on both sides. This structural form can be used to break up the airflow and reduce the wind speed, thereby reducing the impact of the airflow formed inside the dust removal system.

[0027] like Figure 3 , 4 As shown, in order to reduce the impact of airflow, protect the filter element of the dust removal system, and reduce filter element wear, and for the convenience of assembly, the dirty air guide component 3 includes a guide plate 31 and a guide plate mounting seat 32, and the guide plate mounting seat 32 is arranged in the dirty air guide chamber 2, and the guide plate 31 and the guide plate mounting seat 32 are detachably connected.

[0028] Furthermore, for ease of installation and manufacturing, the guide plate 31 of the present invention is a U-shaped piece or a diamond-shaped piece, and the guide plate 31 is an integral piece formed by bending, or a molded piece assembled or welded from multiple connecting plates.

[0029] like Figure 1 As shown, in order to meet different technical requirements and be applicable to different environments, when there are multiple dust removal systems and they are arranged linearly, the air intake chamber of the utility model can simultaneously supply air to multiple dust removal systems, and the air intake chamber 1 has multiple branch chambers 12 connected to its main body, and each branch chamber 12 is connected to the dirty air guide chamber 2. At this time, the dirty air guide chamber 2 is also provided with multiple groups of multiple rows of staggered dirty air guide components 3, and at the same time, the air outlet of each branch chamber 12 is arranged opposite to a group of multiple rows of staggered dirty air guide components 3 in the dirty air guide chamber 2. That is, each dust removal system is connected to a branch chamber 12, so that during use, the dirty air can be diverted to the corresponding dust removal system by using the branch chamber 12 for dust removal and filtration.

[0030] like Figure 1As shown, in order to prevent the excessive temperature of dirty air from damaging the filter element of the dust removal system, the utility model also includes a fire fighting unit 4 for cooling the dirty air, and the fire fighting unit 4 includes a nitrogen fire fighting pipe 41 and a temperature sensor 42, the nitrogen fire fighting pipe 41 is connected to the air inlet chamber 1, and the air inlet chamber 1 is equipped with a temperature sensor 42 for detecting the temperature of dirty air. The temperature sensor 42 forms an interlocking control with the nitrogen fire fighting unit, and when the temperature detected by the temperature sensor exceeds the set value, the system alarms, and nitrogen enters the air inlet chamber 1 through the nitrogen fire fighting pipe 41, effectively cooling the dirty air with excessively high temperature, which can effectively avoid fire.

[0031] like Figure 1 As shown, in order to facilitate the subsequent inspection and maintenance of the air intake chamber and to facilitate the cleaning of dirt on the inner wall of the air intake chamber, the air intake chamber 1 has an inspection door 5, and the inspection door 5 is sealed and connected to the opening of the air intake chamber 1.

[0032] like Figure 1 As shown, in order to realize multi-point temperature detection on the air inlet of the air inlet chamber and each branch chamber to ensure the stability of the system dust removal, the utility model also includes a fire fighting unit 4 for cooling the dirty air, and the fire fighting unit 4 includes a nitrogen fire fighting pipe 41 and a temperature sensor 42. The nitrogen fire fighting pipe 41 is connected to each branch chamber 12 of the air inlet chamber 1, and a switch valve is also provided at the connection between the nitrogen fire fighting pipe 41 and the branch chamber 12, which can automatically control the connection and disconnection between the nitrogen fire fighting pipe and the branch chamber. The air inlet 11 of the air inlet chamber 1 and each branch chamber 12 are provided with a temperature sensor 42 for detecting the temperature of the dirty air.

[0033] like Figure 1 As shown, in order to facilitate the inspection and maintenance of each branch chamber, each branch chamber 12 of the air inlet chamber 1 is provided with an inspection door 5 which is sealed therewith, and at the same time, the connection between each branch chamber 12 and the main body of the air inlet chamber 1 is an arc-shaped angle transition connection, which can reduce resistance and make the airflow flow more smoothly.

[0034] Furthermore, a connecting flange is provided at the bottom opening of the branch chamber 12 , and the connecting flange is detachably connected to the flange of the air inlet of the dirty gas guide chamber 2 .

[0035] Furthermore, the top surface of the air intake chamber 1 is designed to be inclined, that is, the top is inclined at 2° to 4°, which can prevent the top of the air intake chamber from rusting due to accumulated water.

[0036] The utility model is installed as a whole on the top of the dust removal system 6, and the dirty air guide chamber 2 is connected to the air inlet set on the top of the dust removal system 6, which increases the air intake contact surface. At the same time, after the dirty air enters the dirty air guide chamber 2 through the air intake chamber 1, it is dispersed under the action of the dirty air guide component 3, allowing the airflow to evenly reach all the filter elements inside the dust removal system 6, which not only reduces the impact of the airflow and protects the filter element of the dust removal system, but also reduces the wear of the filter element and extends the service life. If the temperature sensor 42 detects that the dirty air temperature exceeds the set value, the system alarms, and the nitrogen fire fighting pipe 41 is connected to the nitrogen to cool the gas to prevent the high temperature from burning the filter element and causing a fire.

[0037] Therefore, the top air intake bus of the utility model can be used in dust removal environments with large air volume, large dust content, abrasive dust, sticky dust, etc. When in use, it is set as a whole on the top of the dust removal system used with it. This structure can not only allow the airflow to be evenly reached to all filter elements after breaking up and reducing the wind speed, and will no longer have the situation where the filter elements at the dirty air inlet are concentrated, but also avoids the situation in which the dust removal system in the prior art is affected by the excessive structural size of the side air intake, which affects its own strength and aesthetics, effectively protects the filter element of the dust removal system, reduces its wear and tear, and extends its service life.

[0038] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
